CA1800 Charge Amplifier System The CA1800 Charge Amplifier System conditions and amplifies charge-mode accelerometer signals. It is a rugged, rackmountable instrument designed to be used engine test cell control rooms and other environments where charge-mode accelerometers are used to measure machinery vibration. The CA1800 Charge Amplifier System provides up to eight (8) channels of charge amplification. Each charge amplifier provides a buffered acceleration output signal as well as an integrated (velocity) signal output. Outputs may be configured for either differential or singled ended configurations, and each channel may be configured (at the MTI Instruments factory) for one of three different gain settings to match accelerometer sensitivities.
